Struct Select 

pub struct Select {
    pub states: SelectStates,
    /* private fields */
}

Select represents a select field, like in HTML. The size for the component must be 3 (border + selected) + the quantity of rows you want to display other options when opened (at least 3).

Similar to Radio, Select is a single-choice selector, but the difference is that it does not show the selector unless the “Tab” is open, and only shows the currently selected choice.

Fields

states: SelectStates
